Darboux integrability and rational reversibility in cubic systems with two invariant straight lines

open access: yesElectronic Journal of Differential Equations, 2013
Summary: We find conditions for a singular point \(O(0,0)\) of center or focus type to be a center, in a cubic differential system with two distinct invariant straight lines. The presence of a center at \(O(0,0)\) is proved by using the method of Darboux integrability and rational reversibility.

The cubic differential system with six real invariant straight lines along three directions

open access: yes, 2009
We classify all cubic systems possessing exactly six real invariant straight lines along three directions taking into account their degree of invariance. We prove that there are 6 affine different classes of such systems. For every class we carried out the qualitative investigation in the Poincar´e disc.
